Darkest Dungeon. It's in Early Access, FYI.
It's a party-based RPG roguelike. I like it a lot. It's based around building a roster of adventurers of a variety of classes. It's similar to X-com in that it is split between a roster-management-research-upgrade game area and individual dungeon crawls or missions you undertake with four adventurers from your larger roster.
The exploration/combat gameplay is side-scrolling RPG/adventure. You explore multi-room dungeons, discover treasure, and fight groups of enemies. The battles are turn-based, like early final fantasy games. Your party is arranged in a single-file line rather than a column, however. Each party member functions differently in each of the four slots in that line; the very powerful melee Leper class, for example, can only attack from the front two slots. The vestal class (based on the D&D cleric) is a warrior in the first two rows and a healer in the back two.
The game keeps up the pressure on the player via the stress system; your adventurers constantly gain stress points as the explore the dungeon and fight enemies. After gaining enough stress points, an adventurer will get a semi-permanent debuff psychological condition or, rarely, a permanent buff psychological condition. These major conditions will affect other party members; debuff conditions will fill their stress meters and buff conditions will drain their stress meters.
Your adventurers will also gain negative and positive traits as they are used. These minor psychological traits only affect the party member who has them.
Your party must also carry food and eat every once in a while exploring. Larger dungeons also allow you to set up camp and use camp skills to lower stress levels and regain HP.
The background and character art is great. The overarching visual design is coherent and effective in setting the mood. It seems pretty clear all the art is done by a single person or a small, cohesive team
This game also features a narrator very similar in style to the one in Bastion. The narration is quite bleak, in keeping with the overall feel of the game.
Even though it is in Early Access, the early game is very polished and robust; it doesn't yet feel unfinished to me. The team is adding new content all the time. There are ten classes currently and three more to be added in. I imagine that the team are working mostly on filling out higher level content.
If you like RPGs or roguelikes, I highly suggest this game. It is moody, tactical, and great fun.
